| Abstract | One hundred and eighty 4-week-old Bresse cockerels were allotted into 6 groups of 3 replications/group according to a2x3 Factorial in a Completely randomized design. The main factor was traditional vs. custom or developed caponizing toolswhile the sub-factor was the age of the birds at castration i.e., 4, 6, and 8 weeks of age. All birds were raised on a highland farmin Thailand until 12 weeks old before slaughtering and carcass evaluation. Using the custom tools significantly decreased(P<0.05) incision size, caponizing time, mortality rate, and slip. At the same time the birds significantly increased average dailygain and feed intake but no significant differences on feed conversion ratio and carcass quality. Early age castration by thecustom tools improved the efficiency and bird performance. In conclusion, the Laparoscopic vacuum testectomy technique canbe done at 4 weeks of age. It minimized incision size, shortened caponizing time, and improved the performance of Bresse caponproduction at a highland farm of the Royal Project Foundation. |
